　　A serious problem for today’s society is who should be responsible for our elderly(老年人) and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.

　　First，

　　employers should take the responsibility for their retired employees. To make this possible，

　　a percentage of profits should be set aside for this purpose. But when a company must take life­long responsibility for its employees，

　　it may suffer from a commercial disadvantage due to higher employee costs.

　　Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.
